Butadiene is flammable, explosive and highly hazardous, and is easy to polymerize when stored at high temperature. Therefore, it is particularly important to maintain the storage of butadiene at low temperature to prevent its polymerization. In order to maintain the low-temperature storage of butadiene and reduce its cold loss, the storage tank usually adopts cold insulation method. The heat absorption calculation of storage tank should not only consider the convective heat transfer with the natural environment, but also the solar radiation heat transfer and the radiation heat transfer in the natural environment. The construction methods for cold insulation layer and external protective layer of spherical tank are not specified in the current specifications. This paper discusses the cold insulation design and heat absorption calculation of storage tank, analyzes the heat absorption calculation of storage tank through examples, and puts forward some methods for reference for the construction of cold insulation layer and protective layer of spherical tank.
